Specific embodiment
In order to develop a kind of filler that can substitute eider down, the invention provides the fluffy processed filament being made up of PLA long fibre or polypropylene filament that a kind of bulkiness is excellent, wherein containing doughnut.According to IDFB test benchmarks, the fluffy degree of the processed filament is 350inch3/ 30g~750inch3/30g.Fluffy degree numerical value is bigger, represents that the space of the air layer that processed filament is formed is bigger, and heat-insulating property is better.Meanwhile, fluffy degree is higher, and feel is more soft.
Fluffy processed filament of the invention is made up of two parts of sheath fiber and core fibre, sheath fiber and core fibre are all the long fibres formed by PLA or polypropylene, cause sheath fiber by the jet-action of compressed air and core fibre intersects and sheath fiber forms annular shape outside core fibre.Due to the empty effect of pressure, the fibre bundle of sheath fiber is separately formed many single fibers, and the sheath fiber passes perpendicularly through the multiple round annular that sheath fiber while core fibre beam forms crosspoint constitutes 3 D stereo back and forth.What the crosspoint that sheath fiber and core fibre are formed not was fixed together melts point, but can move within the specific limits.When the fluffy processed filament is used as packing material, extruded by external force and deform, the crosspoint of fluffy silk can occur certain displacement to absorb external force during deformation, after external force is removed, again can significantly recoverability.
When the polymer for constituting fluffy processed filament is PLA, the fluffy degree of the processed filament is measured as 350inch in IDFB methods3/ 30g~700inch3/30g.When the polymer for constituting fluffy processed filament is polypropylene, the fluffy degree of the processed filament is measured as 400inch in IDFB methods3/ 30g~750inch3/30g。
Constitute the filament number preferably 3.0dtex~10.0dtex of the sheath fiber of fluffy processed filament.Although too carefully the flexibility of fiber increases filament number, the voltage endurance capability of the annulus that sheath fiber is formed can decline on the contrary；Conversely, bigger the had rigidity of the filament number of fiber is higher, obtained fluffy processed filament will be partially hard, and feel is deteriorated.So the filament number that the present invention forms the sheath fiber of the processed filament is more preferably 4.0dtex~8.0dtex.
Preferred 30dtex~the 300dtex of total fiber number of the core fibre.
Radius preferred 2mm~12mm of the sheath fiber in the outer annulus for being formed of core fibre.The fibroplastic circle diameter of sheath is too small, and the volume of the solid space of formation is just small, causes the bulkiness of processed filament not enough, and the clothing or bedding after being filled with it are stronger, do not have the fluffy sense of eider down, and heat-insulating property can also decline.Otherwise, although the bulkiness and flexibility of the bigger processed filament of the fibroplastic annulus of sheath can improve a lot, but resistance against compression can be deteriorated, that is to say, that work silk can form permanent deformation when being extruded by external force, cause degraded performance.Radius more preferably 4mm~9mm of the sheath fiber in the outer annulus for being formed of core fibre.
While number preferably 30~150/cm in the crosspoint that the sheath fiber and core fibre are formed.So-called crosspoint refers to after sheath fiber detaching and core fibre intersects the intersection point to be formed, but the intersection point does not melt together, can move freely.There is correlation in the fibroplastic annulus number of number and sheath in crosspoint.The crosspoint that sheath fiber and core fibre are formed is few, illustrates that the fibroplastic annulus number of sheath is few, then the bulkiness of processed filament is low；Conversely, the crosspoint that sheath fiber and core fibre are formed is more, illustrate that the fibroplastic annulus number of sheath is more, although then the fluffy degree of processed filament increases in certain limit, but the solid space of sheath fiber will not increase, the weight of processed filament unit length increases on the contrary, causes fluffy degree to decline.The number in the crosspoint that the sheath fiber and core fibre are formed more preferably 40~80/cm.
The sheath fiber and core fibre of fluffy processed filament of the present invention can sheath fiber be individually doughnut, core fibre is solid fibre, or core fibre is doughnut in turn, sheath fiber is solid fibre, it is also possible to sheath fiber and core fibre both doughnut.Of the invention preferably sheath fiber and core fibre both doughnut.Compared with solid fibre, the density of doughnut is smaller, under same processing filament shapes and grammes per square metre, the length of fluffy processed filament is longer as obtained in doughnut, be more beneficial for improving the fluffy performance of fluffy processed filament.But requirement of the degree of hollowness doughnut too high to production technology is high, and productivity is low.Degree of hollowness in the present invention preferably as sheath fiber and the doughnut of core fibre is respectively 20~50%, more preferably 25%~40%.
When core fibre is solid fibre, its fracture morphology can also be the special-shaped sections such as triangle, cross, eight leaves in addition to circle.
Simultaneously in order to improve the fluffy degree of fluffy processed filament, sheath fiber preferred curvature radius of the invention for 5mm~20mm it is unwinding after helically 3 D stereo shape crimped filament, the radius of curvature is the radius of the unwinding rear screw of sheath fiber.If the radius of curvature of the sheath fiber is too small, fibrillation is difficult in fluffy silk process mesotheca fiber, and the diameter of annulus that sheath fiber is formed is less than normal, influences the bulkiness of processed filament；Conversely, the radius of curvature of sheath fiber is too greatly, the fibroplastic circle diameter of sheath is excessive after being processed into fluffy processed filament, can weaken or cannot embody the three-dimensional stereo effect of sheath fiber script.
Fluffy processed filament of the present invention can be prepared via a method which to obtain, but be not limited to the method：
Sheath fiber and core fibre are fed by different feeding roller or feeding roller respectively, adjusts the feeding speed of sheath fiber and core fibre to control the filament length difference of sheath fiber and core fibre；According to the difference of sheath fiber, core fibre and bulkiness processed filament kind, the length of sheath fiber is 5~50 times with core fibre length.Air velocity at nozzle is set at 30L/ point~150L/ points, sheath fiber and core fibre with the nozzle that is drawn through of air-flow, then core fibre and sheath fiber in jet expansion source as the effect of chaotic air-flow forms interlacing.The chaotic air-flow is that interference by sheath fiber and core fibre to compressed air causes the flow direction of the compressed air of single flow direction originally to become chaotic, and the chaotic air-flow is in cyclically-varying, sheath fiber carries out fibrillation with chaotic air-flow, and core fibre forms periodically intersection, forms fluffy processed filament.
In order to further improve the flexibility of processed filament, can be with the softening agent of attached last layer silicon systems on the surface of fluffy processed filament.According to sheath fiber and the difference of core fibre surface area, silicone oil adhesion amount is also different, while the adhesion amount scope of the purposes difference softening agent according to fluffy silk is 0.1wt%~5.0wt%.
The fluffy degree of fluffy processed filament of the present invention is high, soft, and due to being fluffy silk that long fibre is constituted, the heat insulating products such as the clothes being made, quilt have the advantages that not leak suede, do not bore suede.There is biological decomposition when raw material is using PLA long filament, the advantage small to environmental pressure.Have the advantages that there is light weight while more preferable heat insulating ability when raw material is using polypropylene filament.
